Multi‐decadal climate and fishing predictors of abundance for U.S. South Atlantic coastal fishes and invertebrates
Abstract Abundance of marine stocks fluctuates in response to both internal processes (e.g., density dependence) and exogenous drivers, including the physical environment, fishing, and trophodynamic interactions. In the United States, research investigating ecosystem drivers has been focused in data...
